  • Patent number: 9809842
    Abstract: Systems, devices, and methods for accurately imaging chemiluminescence and other luminescence are disclosed. A compact, flat-bed scanner having a light-tight enclosure, one or more detector bars of linear charge-coupled device (CCD) or complementary metal oxide semiconductor (CMOS) imaging chips, and high working numerical aperture (NA) optics scans closely over a sample in one direction and then the opposite direction. Averages or other combinations of intensity readings for each pixel location (x, y) between the two or more passes are averaged together in order to compensate for luminescence that varies over time. On-chip pixel binning and multiple clock frequencies can be used to maximize the signal to noise ratio in a CCD-based scanner.

  • Patent number: 7280205
    Abstract: A spectral filtering apparatus and method is presented, which enables the functions of hyperspectral imaging to be performed with increased speed, simplicity, and performance that are required for commercial products. The apparatus includes a photosensitive array having a plurality of photosensitive elements such that different subsections of photosensitive elements of the array receive light of a different wavelength range of a characteristic spectrum of a target, and output electronics combines signals of at least two photosensitive elements in a subsection of the array and outputs the combined signal as a measure of the optical energy within a bandwidth of interest of the characteristic spectrum.
